This is because they use  traditional farming practices with minimal inputs on  traditional varieties or landraces. Use of hybrid  seed was first reported in maize in the 1920s.  Hybrid varieties have an advantage of beign uniform  and more vigorous. This is due to the heterosis that  comes about by crossing genetically divergent parent  lines. Heterosis (for any trait)can be summed up as  superiority of hybrid offspring over best parent. In  this study, a selected set of genotypes is evaluated  in the US and Southern Africa to evaluate the level  of haterosis for yield and other important agronomic  characters of sorghum. The results indicate presence  of significant heterosis that can be used by  researchers to release new higher yielding sorghum  hybrids for the benefit of all sorghum growers in  the region. The author would like to thank Texas A\u0026amp;M  Department of Crop Science for all the work that was  done to bring out this information.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783844380415\"\u003e\u003ch3\u003eThe advantages of using hybrid varieties is highlighted...\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783844380415","offer_id":39470052507741,"sku":"9783844380415","price":49.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/f5a45e08-e0c3-4dc0-a660-2bf6c5e2d149.jpg?v=1758088381","url":"https:\/\/shop.autorenwelt.de\/products\/hybridisation-to-exploit-heterosis-in-sorghum-in-southern-africa-von-leo-mpofu","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
